DETAILED DESCRIPTION

The following detailed description is directed to certain specific embodiments of the invention. However, the invention may be embodied in a multitude of different ways as defined and covered by the claims.

Embodiments of the invention can provide the features of a protection system for a portable or handheld electronic device (hereinafter “handheld electronic device”). Some embodiments of the invention desirably may incorporate an attachment region for attaching a removable mounting member preferably able to support the handheld electronic device within the protection system and affix to a variety of surfaces. Other embodiments of the invention may also incorporate an anti-slip surface wherein a magnet is disposed for attachment of the device to magnetic surfaces and slip prevention.

A preferred embodiment of the present invention comprises a shell for rigidly securing and protecting a handheld electronic device. In a preferred embodiment, the shell may be in multiple pieces for ease of assembly around a handheld electronic device. The upper piece of the shell preferably provides an attachment region for a removable mounting member that can attach to various solid surfaces, such as but not limited to a desk, vehicle dashboard, mirror, etc. The shell preferably also incorporates an anti-slip insert in which a magnet is disposed, allowing for magnetic adherence to surfaces without interfering with the anti-slip benefit provided by the anti-slip insert. The shell preferably is formed using a material that is generally rigid and lightweight, such as but not limited to an injection molded polycarbonate or other suitable plastic material(s). Preferably, the shell comprises rigid sidewalls that surround an entirety or portions of the peripheral edges of the device. The sidewalls preferably are arranged to protect the device by absorbing incidental shock forces and/or inhibiting or preventing direct contact between the device and another object. The sidewalls also desirably contain various openings to allow access to the control buttons, inputs, and outputs of the handheld electronic device. The rear surface of the shell is preferably further designed with various openings to allow additional access to features of the handheld electronic device that may be located on the rear of the device (such as a camera) or to reduce the weight of the shell.

FIG. 1 depicts a preferred embodiment having certain features, aspects and advantages of the present invention. In FIG. 1, protection system 100 may include more, fewer or different components than those shown. Protection system 100 includes a body or shell that, in the illustrated arrangement, is comprised of an upper shell piece 102 and lower shell piece 104. Protection system 100 is shown in two pieces to facilitate installation of the protection system 100 on a handheld electronic device. Lower shell piece 104 is designed, in one embodiment, to fit together with upper shell piece 102 preferably using an interlocking or tab/slot attachment. However, in other arrangements, the upper shell piece 102 and lower shell piece 104 could be secured together with other arrangements (e.g., mechanical fasteners, such as screws) or could be portions of a unitary or single-piece shell in which installation of the electronic device is accomplished through another method, such as by deformation of the side walls or other portions of the shell to pass over the electronic device. Thus, references to the upper shell piece 102 or lower shell piece 104 herein are also intended to refer to the entire shell of an integrated or unitary shell arrangement.

Upper shell piece 102 preferably includes an attachment region 106 for attaching mounting member 108. The attachment region 106 contains an engagement structure that allows the upper shell piece 102 and, thus, the protection system 100 to be releasably attached the mounting member 108. A preferred engagement structure is described in greater detail below. As shown in FIG. 1 and FIGS. 9A-C, mounting member 108 may be comprised of an interlocking member 902 and at least one mounting base 904. As described further below and shown in FIG. 6, the mounting member 108 can also include one or more optional spacers, which could be similar or identical to the mounting base 904. Upper shell piece 102 also preferably includes a non-slip region 110, which includes a non-slip arrangement that enhances frictional engagement of protection system 100 with a surface on which the protection system 100 may be placed. In the illustrated arrangement, the non-slip region 110 incorporates an opening or cavity in the protection system 100 (e.g., the upper shell piece 102) into which non-slip member 112 may be inserted. As depicted more clearly in FIG. 8C, non-slip member 112 may also preferably comprise a rare earth magnet 802 in order to removably attach the handheld electronic device contained within protection system 100 to a magnetic surface.

FIG. 1 further depicts a preferred embodiment of the invention further comprising a lanyard 140, which may attach to protection system 100 to facilitate easy carrying and transport of a handheld electronic device. For example, the lanyard 140 can be looped through openings 142 and 144 on the upper shell piece 102 and lower shell piece 104, respectively. Additional accessories, not shown in FIG. 1, may be used with protection system 100. For example, one accessory that may be used with protection system 100 includes a bike mount, one embodiment of which is shown in FIG. 11. Another accessory that may be used with protection system 100 includes a tripod (not shown), which can support the protection system 100 and associated electronic device in a suitable position (e.g., portrait or landscape) preferably at an elevated position relative to a surface on which the tripod rest to take photographs or video. The accessory can be coupled to the protection system 100 via an interlocking arrangement the same as or similar to the mounting member 108 or via other suitable arrangements, such as the same as or similar to the lanyard 140 arrangement. In addition to the lanyard 140, bike mount and tripod, other types of accessories can also be provided, such as adjustable or non-adjustable stands, mounting or securing clip arrangements, etc.

As shown in FIGS. 1-4, the assembled upper shell piece 102 and lower shell piece 104 of the protection system 100 together define an interior region or space in which a handheld electronic device may be enclosed. Each of the upper shell piece 102 and the lower shell piece 104 has a rear wall portion 200 that defines an interior rear surface 202 positioned adjacent the back surface of an electronic device placed in the protection system 100. The upper shell piece 102 and the lower shell piece 104 also include at least one or a plurality of enclosing edges to surround the sides of a handheld electronic device and provide protection for the handheld electronic device. In the illustrated arrangement, the enclosing edges are defined by a sidewall portion 150 that extends from the rear wall portion 200. The illustrated sidewall portion 150 extends along an entire periphery of the rear wall portion 200. As described above, however, the sidewall portion 150 is not necessarily solid or continuous, but can include one or more openings configured to allow access to controls or other components or features of the handheld electronic device, or simply to reduce weight. In alternative arrangements, the sidewall portion 150 can be constructed of one or several distinct sidewall portions, such as four corner portions, for example. A forward wall portion is spaced from the rear wall portion 200 by the sidewall portion 150. The forward wall portion defines a forward interior surface that is positioned adjacent a forward surface of the handheld electronic device placed in the protection system 100. In the illustrated arrangement, the forward wall portion is defined by a lip 152 that extends in an inward direction from the sidewall portion 150. Preferably, the lip 152 extends around the entire periphery of the rear wall portion 200. However, in other arrangements, the lip 152 can extend only around a portion of the periphery, which can be the same portion or a different portion than the portion surrounded by the sidewall portion 150. As discussed above, the upper shell piece 102 and lower shell piece 104 can be unitarily-formed. Accordingly, the sidewall portion 150 and/or lip 152 could be unitary, as well.

As more clearly illustrated in FIG. 2, upper shell piece 102 also preferably includes an attachment region 106. The illustrated attachment region 106 defines an opening 160 in the interior rear surface 202 of upper shell piece 102. As described above, attachment region 106 is configured to allow attachment of mounting member 108 through an interlocking attachment that selectively secures the shell 102 to the mounting member 108 an inhibits or prevents removal in at least one direction. As pictured, attachment region 106 comprises at least one tab 162, each of which preferably defines two interlocking surfaces, 116 and 126. In the illustrated arrangement, the attachment region 106 includes four tabs 162; however, other numbers of tabs 162 could also be provided, such as two, three, five, six or more tabs 162. Interlocking surface 116 is disposed towards the interior rear surface 202 of upper shell piece 102, while interlocking surface 126 is disposed within a different plane than that defined by interlocking surface 116. Preferably, the interlocking surface 116 is perpendicular or substantially perpendicular to the interlocking surface 126. Preferably, the interlocking surface 116 is perpendicular or substantially perpendicular to the interior rear surface 202. The plane of interlocking surface 126 preferably is offset or disposed “below” the plane defined by the interior rear surface 202 or towards the outer rear surface of upper shell piece 102. In addition, preferably, the interlocking surface 116 is offset from at least a portion of the interlocking surface 126 in a circumferential direction to provide a space 164 in which a portion (e.g., tab 912) of the interlocking member 902 may be inserted. The opening 160 preferably also includes at least one access space 166 located beside or circumferentially offset from the at least one tab 162. Preferably, the number of access spaces 166 corresponds to the number of tabs 162. In the illustrated arrangement, four access spaces 166 are provided; however, the number of access spaces 166 can vary in the same manner as the number of tabs 162. Each of the tabs 912 of the interlocking member 902 can be inserted through one of the access spaces 166 and then turned to enter the space 164 and rest against the interlocking surfaces 116 and 126 to form an attachment with upper shell piece 102. Preferably, the access opening 166 is located on an opposite side of the interlocking surface 126 from the interlocking surface 116. In the illustrated arrangement, a circumferential dimension of the access opening 166 is smaller than a circumferential dimension of the tab 162 and can be approximately one-half of the circumferential dimension of the tab 162. The circumferential dimension of the space 164 is less than the circumferential dimension of the tab 162 and can be approximately one-half of the circumferential dimension of the tab 162. In the illustrated arrangement, the interlocking surface 116 is defined by a rib 168 that extends at least partially, and preferably entirely, around the opening 160. Preferably, the opening 160 passes completely through the upper shell piece 102 such that the surface of the associated electronic device is exposed through the opening 160. Such an arrangement advantageously minimizes the overall thickness of the protection system 100, while still providing the desired interlocking mount functionality. In an alternative arrangement, however, a rear wall portion can be provided to define a closed internal end of the opening 160, such that the rear wall portion is positioned in between the interlocking mount and the associated electronic device. Such an arrangement may increase the overall thickness of the protection system 100, but can also provide increased protection to the associated electronic device.

The interior rear surface 202 preferably also includes a non-slip region 110 within which a non-slip arrangement can be provided. For example, a non-slip member 112 may be inserted within the non-slip region 110 of the protective device 100. As shown, non-slip region 110 is comprised of a smaller opening 120 disposed within a larger opening 130. In the illustrated arrangement, the smaller opening 120 extends completely through the rear wall portion 200 and the larger opening 130 extends partially through the rear wall portion 200 from the interior rear surface 202. The recessed surface formed by the disposition of smaller opening 120 within larger opening 130 forms an interference surface to retain non-slip member 112 within the non-slip region 110. FIG. 2 shows one orientation of attachment region 106 and non-slip region 110, though other embodiments may include different orientations. A number of additional open spaces (generally 170) may be provided in the interior rear surface 202 of upper shell piece 102 for any of a number of reasons, including providing access to rear-mounted features of a handheld electronic device such as a camera, microphone, or speaker, or to reduce the weight of the protection system 100. Upper shell piece 102 may further comprise one or more of recesses 204 configured to accommodate one or more tabs 206 to facilitate attachment and retention of lower shell piece 104 to upper shell piece 102 to provide further protection for a handheld electronic device. In the illustrated arrangement, a pair of recesses 204 are located on the rear wall portion 200 of the upper shell piece 102 and a pair of tabs 206 are located on the rear wall portion 200 of the lower shell piece 104. However, in other arrangements, the recesses 204 and tabs 206 could be located elsewhere (e.g., sidewall 150 or front wall/lip 152) and/or could be provided in different numbers. In addition, the arrangement could be reversed such that the tabs 206 are provided on the upper shell piece 102 and the recesses 204 are provided on the lower shell piece 104.

One embodiment of the exterior rear surface 302 of upper shell piece 102 is pictured in FIG. 3. The attachment region 106 as viewed from the rear of upper shell piece 102 is preferably disposed above or outwardly of the plane defined by at least a portion of the exterior rear surface 302, which can be a peripheral portion. In a preferred embodiment, the attachment region 106 has an opening 160 defined by a plurality of equally spaced radial lobes or tabs 162 designed to correspond with the tabs 912 of an interlocking member 902, more clearly viewed in FIGS. 9A and 9B. Mounting member 108 attaches to the exterior rear surface 302 side of the rear wall portion 200 of the upper shell piece 102 of protection system 100 preferably via an interlocking attachment. Once inserted, the tabs 912 of the interlocking member 902 may then rotate until further rotation is prevented by the interlocking surface 116, as seen in FIG. 2. After rotation, the tabs of interlocking member 902 will preferably be located adjacent to the interior side of interlocking surface 126 and against the edge of interlocking surface 116, forming an interlocking connection which preferably attaches mounting member 108 to the upper shell piece 102 of protection system 100.

Preferably, non-slip region 110 will also be disposed above the plane defined by exterior rear surface 302, as seen in FIG. 3. In the illustrated arrangement, when inserted, the non-slip member 112 will protrude outwardly as far as or further than any other rearward surface portion of the protection system 100 such that the non-slip member 112 will contact a surface upon which the protection system 100 is placed (assuming the surface is relatively flat or otherwise appropriately shaped) to accomplish a non-slip function. Therefore, when non-slip member 112 is disposed within non-slip region 110, the non-slip surface will extend beyond at least the plane of exterior rear surface 302 to grip a surface and provide a non-slip feature.

A perspective view of a preferred embodiment of upper shell piece 102 is pictured in FIG. 4. In this view, the different surfaces of attachment region 106 are more clearly visible. As described above with respect to FIG. 2, interlocking surface 116 is disposed towards the interior rear surface 202 of upper shell piece 102 relative to the interlocking surface 126, while interlocking surface 126 is disposed “below” the plane defined by interlocking surface 116, or towards the outer rear surface of upper shell piece 102. As is more clearly seen in FIG. 4, the interlocking surface 116 is circumferentially offset from the access opening 166 to provide the space 164 in which an interlocking member 902 may be inserted and then turned to form an attachment with upper shell piece 102. The rotation of the interlocking member 902 within attachment region 106 forms an interlocking connection with the upper shell piece 102. This interlocking connection is defined by the tabs 912 of the interlocking member 902 passing without obstruction into the defined areas (e.g., access openings 166) of attachment region 106 and then rotating against the interior surface of interlocking surface 126 until the tabs of interlocking member 902 are prevented from further rotation by encountering the interlocking surface 116. After rotation, the interior-facing surfaces of the interlocking member 902 and the interlocking surface 116 preferably will be substantially within the same plane.

FIG. 4 also more clearly depicts a preferred embodiment of the non-slip region 110 and openings 120 and 130. The smaller opening 120 is disposed within the larger opening 130. A small lip or ridge 180 is formed by the overlap of the two openings because the larger opening 130 is disposed towards the interior rear surface 202 of upper shell piece 102. Preferably, this lip or ridge 180 is disposed beneath the plane of the interior rear surface 202. The flexible non-slip member 112, such as that described in greater detail below with regard to FIGS. 8A-C, may be disposed within the non-slip region 110. An interior portion of the non-slip member 112 preferably has a greater diameter than the smaller opening 120 but also has a diameter sized to fit within larger opening 130. When inserted into the non-slip region 110, the larger diameter of the interior surface prevents the non-slip member 112 from falling out of the non-slip region 110. The smaller diameter of opening 120 will substantially prevent the non-slip member 112 from falling out of the non-slip region 110. The opening 120 defined by the non-slip region 110 will therefore allow a portion of the non-slip member 112 to contact a surface. The inclusion of the non-slip member 112 into protection system 100 provides non-slip properties and benefits to the protection system 100, such as preventing a handheld electronic device within the protection system from sliding off a smooth surface such as a desk or counter. The non-slip member 112 can include a peripheral recess 182 that is configured to receive the lip 180 to more securely hold the non-slip member 112 within the opening 120.

Lower shell piece 104 is shown in FIG. 5. In a preferred embodiment, lower shell piece 104 comprises an interior surface and side surfaces that surround the lower sides of a handheld electronic device to provide additional protection. Lower shell piece 104 preferably joins with upper shell piece 102 to provide protection around the sides and back of a handheld electronic device. The lower shell piece 104 can contain one or more openings to allow access to controls and ports on the handheld electronic device, such as a headphone jack or microphone jack. Furthermore, lower shell piece 104 also preferably contains an opening 190 to allow access to the charging area and/or microphone and speakers on the handheld electronic device such that the handheld electronic device does not need to be removed from protection system 102 in order to charge the device. FIG. 5 depicts only a preferred embodiment of the invention and other openings not shown may be included.

FIG. 6 illustrates a cross section of upper shell piece 102 and mounting member 108. In this figure, mounting member 108 is affixed to upper shell piece 102 in a preferred embodiment. As shown in this figure, the mounting member 108 is affixed to the rear surface of upper shell piece 102 within attachment region 106. Mounting member 108 extends out from the rear surface 302 of upper shell piece 102 such that protection system 100 may be mounted on a solid surface without being flush against the solid surface. The mounting member 108 depicted in the preferred embodiment is composed of two mounting pieces (e.g., mounting bases 904) joined together, along with an interlocking member 902. Mounting member 108 may be composed of greater or fewer mounting pieces joined together, depending on how far a user desires to mount the handheld electronic device from a solid surface. The interlocking member 902 of the mounting member 108 is joined to the interlocking member 902 preferably via a screw 906, but other forms of attachment may be used. The mounting bases 904 can be joined together by any suitable arrangement (e.g., snap-fit or mechanical fasteners) or the screw 906 could also hold the mounting bases 904 together in addition to securing the interlocking member 902 to the mounting base(s). If desired, an optional adhesive layer 908 can be provided on the rearward surface of the mounting member 108 to allow the mounting member 108 to be adhesively coupled to a desired surface.

A cross-sectional view of a preferred embodiment of protection system 100 containing non-slip member 112 is shown in FIG. 7. In the preferred embodiment shown, the non-slip surface of non-slip member 112 extends in a rearward direction at least as far and, preferably, beyond any other portion of exterior rear surface 302 of upper shell piece 102 (and lower shell piece 104) in order to provide a gripping surface to prevent a handheld electronic device from slipping on a solid surface. The non-slip member 112 also preferably contains a magnetic member, such as a rare-earth magnet 802, as further described below in regards to FIG. 8C. The magnet 802 is positioned or embedded within non-slip member 112 in order to provide a means of attaching protection system 100 to a magnetic surface without impacting the non-slip benefits provided by non-slip member 112 or scratching the surface.

One preferred embodiment of a non-slip member 112 is shown in FIGS. 8A, 8B, and 8C. The non-slip member 112 is composed of a gripping outer surface shown in FIG. 8B and an interior-facing surface, as shown in FIG. 8A. This figure depicts a generally round or cylindrical indentation 192 into which a rare-earth magnet or other magnetic material may be placed without interfering with the non-slip benefits provided by non-slip member 112.

FIG. 8B depicts the exterior-facing surface of non-slip member 112. This figure more clearly illustrates the larger diameter of the interior-facing surface of non-slip member 112 versus the exterior-facing surface. These surfaces are separated by the groove or recess 182, which interacts with the smaller opening 120 in upper shell piece 102, as discussed above with regard to FIG. 4. As discussed above, the larger diameter of the interior surface prevents the non-slip member 112 from falling out of the non-slip region 110 because of interference between the larger diameter of the interior surface of non-slip member 112 and the smaller diameter of opening 120. The exterior surface of non-slip member 112 preferably has a ridged or roughened surface features in order to provide a better gripping surface and prevent the protection system from slipping on a solid surface. The exterior surface may also comprise different logos or other surface textures as desired.

The inclusion of rare-earth magnet 802 into non-slip member 112 is shown in FIG. 8C. This figure illustrates that the rare-earth magnet is preferably inserted into the indentation 192 on the interior surface of non-slip member 112. An optional cover piece 804 preferably made of the same material as non-slip member 112 can be placed on the interior-facing side of the rare-earth magnet 802 to provide a buffer between the magnet and the handheld electronic device within protection system 100.

FIGS. 9A-C illustrate one embodiment of the different components of mounting member 108. As shown in FIG. 9A, interlocking member 902 has a plurality of engaging members 912 located preferably at 90 degree intervals around the circumference of the interlocking member 902. This surface of interlocking member 902 may also display a logo or other information.

The connecting surface of interlocking member 902 is shown in FIG. 9B. Interlocking member 902 is attached to at least one mounting base 904, shown in FIG. 9C, preferably via a screw 906 (FIG. 6) received within a boss 920 of the interlocking member 902. However, other means of attachment may be used to connect the interlocking member 902 to at least one mounting base 904. Preferably, the interlocking member 902 and the mounting base 904 include complementary interference features that locate the interlocking member 902 and mounting base 904 relative to one another in a rotational direction and inhibit or prevent the relative rotation of the interlocking member 902 and the mounting base 904. In the illustrated arrangement, the interference features include a projection 922 and a recess 924, which are generally rectangular in shape but could be other suitable shapes, as well. The projection 922 is positioned on the interlocking member 902 and the recess 924 is located on the mounting base 904; however, these positions could be reversed. The projection 922 and recess 924 locate the interlocking member 902 such that the engaging members or tabs 912 are located in a desirable position relative to corresponding projections or feet 926 on the surface of the mounting base 904 that faces the interlocking member 902. The feet 926 are circumferentially offset from the tabs 912 and contact the tabs 162 of the upper shell piece 102 to provide a stop surface to the rotation of the upper shell piece 102 at a properly aligned position relative to the mounting member 108 when assembled thereto. The illustrated arrangement includes the same number of feet 926 as tabs 912; however, a lesser number of feet 926 could also be used. The circumferential dimension of the feet 926 can be configured such that the feet 926 contact an edge of the access opening 166 to provide some amount of resistance to rotation of the upper shell piece 102 in a directing tending to remove the upper shell piece 102 from the mounting member 108 thereby inhibiting unintentional disconnection of the upper shell piece 102 from the mounting member 108. If desired, active locks could also be provided to prevent unintentional disconnection of the upper shell piece 102 from the mounting member 108.

FIG. 10 depicts one embodiment of an assembled mounting member 108 preferably comprised of two mounting bases 904 and an interlocking member 902. In other embodiments, mounting member 108 may be further comprised of additional mounting bases 904 or a spacer, not shown, between the mounting bases.

The side of interlocking member 902 shown in FIGS. 9A and 10 is inserted into the attachment region 106 formed by interlocking surfaces 116 and 126 by aligning the tabs or engaging members 912 of interlocking member 902 with the access openings 166 in the attachment region 106, as seen in FIG. 2. Preferably rotating or twisting mounting member 108 in a clockwise direction results in the tabs or engaging members 912 of interlocking member 902 rotating behind or inside of interlocking surface 126 until further rotational movement is stopped by interaction with interlocking surface 116. This rotational movement of interlocking member 902 results in the rigid yet removable attachment of mounting member 108 to protection system 100. Similarly, rotation or twisting of interlocking member 902 in the opposite direction allows for removal of mounting member 108.

Attachment or detachment of protection system 100 from the mounting member 108 occurs either through rotation of mounting member 108 (resulting in rotation of interlocking member 902) or through rotation of the handheld electronic device within the protection system 100, as when the mounting member 108 is securely attached to another surface.

With reference to FIG. 11, one accessory that may be used with protection system 100 includes a bike mount 1100. The illustrated bike mount 1100 may be mounted on or as a replacement of the top cap of a bicycle steering stem arrangement, preferably using screw 1120. In particular, the bike mount piece 1110 preferably replaces the top cap of a standard bicycle steering headset system and rests on the upper surface of the front fork steerer tube or steering stem spacer. As is known, the top cap is utilized to adjust a preload of the bearings in the bicycle steering headset system. Once the steering stem is clamped to the steerer tube, the top cap is no longer providing any function. The present bike mount 1100 can replace the standard top cap. Preferably, the mount piece 1110 is adjustable (e.g., rotatable) with respect to the bike mount attachment piece 1130. In particular, in the illustrated arrangement, the bike mount attachment piece 1130 includes an arm portion that extends from the mount piece 1110. The arm portion is rotatably coupled to the mount piece 1110 by a pivot assembly. The bike mount attachment piece 1130 may attach to the upper shell piece 102 using the interlocking mounting arrangement discussed above.
